![]() “Stripe really did come about because we were really appalled by how hard it was to charge for things online.” - John Collison Specifically, the Collisons aimed to more seamlessly connect online businesses and payment processors, allowing more businesses to accept online payments. This growth has created major opportunities in the payments space, and companies like Stripe - a payments unicorn valued at a massive $36B - are hungry to capitalize on them.īrothers Patrick and John Collison founded Stripe in 2010 in an attempt to gain share in online payments, a then-nascent market with seemingly boundless growth opportunities. That is another study in the offing.As businesses and consumers become more comfortable using credit cards online, the proportion of US commerce that takes place online has steadily increased over the last 20 years. While Ranthambhore has been a genetic island for decades, tiger siblings were handpicked from this inbred population for repopulating Sariska. Meanwhile, India’s northwestern tiger population shows higher mean relatedness between individuals (46%) and lower heterozygosity (22%) than even Simlipal (38% and 28%). While airlifting tigers appears to be the solution of convenience these days, there is no alternative to restoring or maintaining natural connectivity between tiger forests in the long term. Hopefully, such studies and the insights they provide will help safeguard the futures of endangered species,” said Ramakrishnan of NCBS.įortunately, introduction of fresh genes in an isolated pool, depending on the number of migrants, frequency of influx and population size, can reverse the damage over time. It has been a fascinating journey to understand pseudo-melanism in Simlipal. ![]() ![]() Overall, such populations have a high chance of extinction. We predict that such populations will be subject to genetic drift (chance events), inbreeding and inbreeding depression (decreased survival). “While tigers have recovered in some parts of India, several populations remain small and isolated. Consequently, mean relatedness between Simlipal individuals (38%) is higher than those in Central (9%) or South India (13%). The loss of genetic diversity is evident from the low heterozygosity - chances of inheriting different forms of a particular gene from each parent - in Simlipal (28%) compared to Central India (36%). The conclusion: Simlipal’s small and isolated tiger population led to inbreeding and the anomalous phenotype characterised by wide, merged stripes. A tiger family at Nandankanan Biological Park, Bhubaneswar, includes (from left to right) the mother (white tigress), white pseudo-melanistic son, orange pseudo-melanistic son, orange regular father (in the back), and orange regular daughter. While previous studies detected three major genetic clusters within Indian tigers-Central India, South India, and Northwest India - the present one found that Simlipal tigers are genetically distinct from other central Indian populations and disconnected at a dispersal threshold of 200 km. Dispersals longer than 500 km have been documented, the study noted, but they are very rare. The closest breeding tiger population to Simlipal is around 800 km away, a distance much longer than the average home range of Bengal tigers (20-110 km) and their average dispersal distance (78-124 km). All of them have ancestral links to one individual from Simlipal. Pseudo-melanistic tigers are also present in three zoos in India - Nandankanan (Bhubaneswar), Arignar Anna Zoological Park ( Chennai) and Bhagwan Birsa Biological Park (Ranchi) - where they were born in captivity.
